ACDBQC54-HF

Overview

The ACDBQC54-HF is an automotive-grade Schottky barrier rectifier manufactured by Comchip Technology. It features a 30V maximum repetitive reverse voltage and a 200mA average forward current rating. The device utilizes a compact SOD-923F (0402C) surface-mount package, designed for space-constrained PCB layouts. Key electrical characteristics include a low forward voltage drop of 800mV at rated current and a maximum reverse leakage current of 6µA. It supports a peak forward surge current of 2A and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Automotive-grade reliability with extended operating temperature range up to +150°C
• Ultra-compact SOD-923F footprint optimized for high-density surface-mount applications
• Low forward voltage drop for improved power efficiency and reduced heat generation
• Guardring structure provides enhanced overvoltage protection and stability

Applications

• Automotive electronics and infotainment systems
• Portable consumer devices requiring minimal board space
• DC-DC converter output rectification
• Power supply freewheeling diodes in low-current circuits

Procurement Notes

Verify the specific suffix and packaging configuration against the official Comchip Technology datasheet prior to ordering. Confirm that the component meets the required automotive qualification standards for your specific application environment. Ensure compatibility with standard reflow soldering profiles for the SOD-923F package to maintain joint integrity.

Selection Notes

Select this component when space constraints necessitate a 0402-sized Schottky diode with automotive-grade temperature resilience. It is suitable for low-voltage, low-current rectification tasks where low forward voltage drop is critical for efficiency. Compare against standard commercial grades if higher surge capability or different voltage ratings are required.

Part Context

This part belongs to Comchip's ACDBQC series of automotive Schottky diodes. The series is characterized by its use of silicon epitaxial planar chips and gold termination technology, which ensures zero tin-whisker potential and robustness during multiple reflow cycles. It complements other small-form-factor rectifiers in the manufacturer's discrete semiconductor portfolio.

Replacement Considerations

Consult official substitution guides for equivalent 30V 200mA Schottky diodes in SOD-923F packages. Verify pinout compatibility and thermal performance metrics before replacing with components from other manufacturers.
